In this review, researchers explored the roles of vitamins A, B3, C, D, and E in skin immunity, highlighting their potential as therapeutics for skin diseases due to their antioxidant, anti-inflammatory, and antimicrobial properties.

This study found that self-noncoding dsRNA activates TLR3 to stimulate intrinsic retinoic acid synthesis, promoting new hair follicle formation in wounded mice and showing similar gene expression changes in humans treated with rejuvenation lasers.

Keratin peptides can change hair shape gently without harsh chemicals.

This review found that low-level laser therapy appears promising in improving hair regrowth and patient satisfaction in androgenetic alopecia, though results should be interpreted cautiously.

This study suggests that variations in PCOS phenotypes observed across different ethnic groups may be due to a genetic gradient resulting from historical human migrations and genetic drift.

This review explores genetic and lifestyle factors influencing hair diversity and reports no new findings, calling attention to the potential for future discoveries in genetic and epigenetic research.

This study found that the vitamin D receptor is essential for the self-renewal, migration, and differentiation of epidermal stem cells during skin wound healing in mice.

This study suggests that down-regulation of vasculature-related genes in dermal papilla cells from balding scalps might contribute to the development of androgenetic alopecia.

This study found that androgen receptor activation in adult mouse skin reduces β-catenin-induced hair follicle growth and sebaceous gland conversion, highlighting its role in stem cell fate decisions.

This study identified thyrotropin-releasing hormone (TRH) as a stimulant of wound healing in both frog and human skin models, suggesting it as a potential neuroendocrine wound repair promoter.

This study found that overexpression of AKR1C3 in prostate cancer cells redirected androgen metabolism towards testosterone production, which facilitated cell proliferation, potentially reducing the effectiveness of finasteride treatment.

This review discusses the broadening scope of botulinum toxin applications beyond traditional uses, highlighting its effects on non-neuronal cells and potential in treating various dermatological conditions, without reporting new clinical findings.

Scarring alopecias are complex hair loss disorders that require early treatment to prevent permanent hair loss.

This study found that the signaling peptide CLE40 and receptor proteins CLV2 and CRN regulate root meristem differentiation through two distinct, antagonistic pathways activated by CLE40 in a dose-dependent manner.

This study suggests that women with polycystic ovary syndrome may have a distinct metabolomic profile, differing in levels of amino acids, organic acids, and lipids compared to controls.

This study suggests that TGF-β 2 plays a critical role in hair follicle morphogenesis and may enhance the effectiveness of future cell therapies for hair regrowth using expanded dermal papilla cells.

This study found that disrupting Smad4 signaling in young mice led to overactivation of follicle stem cells, causing hyperplasia and depletion of the stem cell niche.

This study identified diltiazem, a calcium channel blocker for hypertension, as a promising repurposed treatment for influenza, enhancing antiviral efficacy when combined with oseltamivir.

This review discusses the integration of drug repurposing with personalized medicine through off-label prescribing and reports no new results, highlighting the potential for systematic exploration using omics technologies.

In this study, researchers differentiated induced pluripotent stem cells into cells with dermal papilla-like properties, demonstrating their potential role in hair follicle bioengineering and drug testing for hair growth.

This review explores the role of Eph receptors and ephrins in skin cell processes, discussing their potential for therapeutic targeting in dermatological disorders, but it presents no new research findings.

This review explores the potential (neuro-)endocrine influences on hair follicle epithelial stem cell biology and emphasizes the need for more systematic research, but it provides no new empirical results.

This article discusses the need for rational strategies in developing hair loss drugs targeting specific events in hair follicle cycling, reporting no clinical findings but emphasizing the importance of understanding molecular controls.

This review discusses the mechanisms and engineering techniques for enhancing the targeted delivery of extracellular vesicles in therapies but reports no new clinical findings; the authors encourage further exploration to advance clinical applications.

This review discusses the progress in tooth regeneration research and highlights the potential of spatial-temporal release of developmental factors, but it reports no new clinical findings.

This review summarizes the current understanding of microRNAs in skin biology, highlighting their roles in processes like wound-healing and aging, without presenting any new experimental results.

This study identified three genes with significantly higher expression in androgen-sensitive beard dermal papilla cells compared to androgen-insensitive scalp cells, suggesting potential novel signaling pathways in hair follicles.

The researchers reported that in mice, prolactin signaling in the skin epithelium inhibits hair follicle stem cell activation, promoting quiescence during periods of high serum prolactin like pregnancy and lactation.

This study revealed that deficiency in the enzyme FA2H in mice affected sebaceous gland function, altered sebum composition, and caused cycling alopecia, highlighting FA2H's role in hair follicle homeostasis.

This review discusses pyrene excimer nucleic acid probes for detecting biomolecules and protein-DNA interactions and reports no new experimental findings.
